Souta's older sister comes across as intimidating at first, but she's genuinely devoted to him—probably because they lost their mother young and had to lean on each other. She and Souta are close, often reminiscing about their childhood and the house they grew up in together, which she clearly regrets having to leave behind. Those memories seem to weigh on her, especially since she remembers their mother better than he does.
She's admitted she feels bad about never giving their father grandchildren, even though it was ultimately her own choice. When it comes to kids in general, she's not a natural—but her time with Poco and Souta changed that for her. She worries about him constantly and tends to carry a sadness when they talk about the past, a heaviness that probably stems from how much she misses those earlier days.
